Hi all,
I was doing performance testing on M-E-C the other day and encounter this problem. I tried sending 2000 files in 4 batch (500 file per batch) to our M-E-C server. Size of each file varies from 1kb to 4kb. However after I have finish sending, I notice M-E-C seems to be struggling to send out all the MDN messages. I suspect the MDN message creation part is slowing it down but no prove on that yet. The worse comes when after processing half of the messages, M-E-C just seems to stop responding. The UI still responds but it seems M-E-C has stopped creating any MDN. After leaving it alone for some time and still no activity, I decided to restart it. Upon restart, no recovery is done and all the messages still show pending.
Sorry for the long post but can anybody give some insight of what might be happening? Thanks a lot.
Just to add, I'm running b23
all_insane,
could you please update to b25? Does this problem still exist (please reserve more memory for this test than default).
Regards

Hi heller,
This problem still exists and 512Mb is allocated to mec as2. Does b25 has auto-recovery function? Will messages that hasn't being replied to with MDN be reprocessed?
all_insane,
That is only possible for async MDN but hasnt been implemented so far.
Have you tested with sync MDN? Please try to switch to async MDN for heavy load, this requires less resources.
Regards
Heller
Hi heller,
Sorry, forgot to mention that I am currently running it in ASync MDN mode. I was monitoring the UI when it stop processing. After leaving it alone for around 45 minutes and recheck, I still see the same number of messages pending to be replied. Will the reprocessing feature be turned on in the next release? That will help a lot~! Thanks.
